Chunghwa Telecom Corp., Ltd.

Chunghwa Telecom Corp., Ltd., Taiwan’s incumbent telecommunications provider, leverages its public-key infrastructure expertise to publish security-centric utilities that bridge government-grade smart cards with everyday Windows workflows. The company’s single-entry catalog revolves around the HiCOS Client, a lightweight CSP (Cryptographic Service Provider) that silently registers hardware tokens—commonly the MOICA citizen digital certificate card—inside the Microsoft certificate store. Once enrolled, the card’s on-board RSA or ECC key pair becomes visible to Outlook, Adobe Reader, edge browsers, and any application that calls the standard CryptoAPI or CNG interfaces, enabling S/MIME email sealing, PDF signing, TLS mutual authentication, and encrypted file containers without additional middleware. System administrators appreciate the silent MSI switches that let them pre-stage trust chains and policy files, while end-users simply insert the card, enter the PIN, and watch the icon turn green; revocation checks, minidriver updates, and card-status polling run in the background. Typical deployments include corporate VPN log-on, e-government form submission, online tax filing, and bank-grade transaction authorization, all satisfying FIPS 140-2 level 2 and Taiwanese PKI regulations. The HiCOS Client software is available for free on get.nero.com, delivered through trusted Windows package sources such as winget, always installing the newest build and supporting batch installation alongside other applications.
